Day 1 — Arrival in Frankfurt: easy start, Main riverfront, and early rest
✈️ After arriving in Frankfurt, it’s best not to try to do a full sightseeing program right away. From the airport to the city center, it is usually convenient to take the S-Bahn or a taxi; allow about 30–45 minutes to get to the hotel, including waiting time, baggage, and transfers. For families with children, the ideal scenario is “check in → eat → take a short walk by the water → go to bed early.” The Main river embankments are great for a first walk: wide views, boats, bridges, the feeling of a big city, but without overload. This is not a day for heroic efforts, but for adaptation — if the child is rested and calm on the first evening, the rest of the route goes noticeably more easily.
